Visualization of the flat electronic band in twisted bilayer graphene near the magic angle twist
M. Iqbal Bakti Utama, Roland J. Koch, Kyunghoon Lee +15
Bilayer graphene was theorized to host a moire miniband with flat dispersion if the layers are stacked at specific twist angles known as the magic angles. Recently, such twisted bi…
Topological flat bands without magic angles in massive twisted bilayer graphenes
Srivani Javvaji, Jinhua Sun, Jeil Jung
Twisted bilayer graphene (TBG) hosts nearly flat bands with narrow bandwidths of a few meV at certain {\em magic} twist angles. Here we show that in twisted gapped Dirac material b…
Relaxation Effects in Twisted Bilayer Graphene: a Multi-Scale Approach
Nicolas Leconte, Srivani Javvaji, Jiaqi An +2
We present a multi-scale density functional theory (DFT) informed molecular dynamics and tight-binding (TB) approach to capture the interdependent atomic and electronic structures…
Metallic Network of Topological Domain Walls
Tao Hou, Yafei Ren, Yujie Quan +3
We study the electronic and transport properties of a network of domain walls between insulating domains with opposite valley Chern numbers. We find that the network is semi-metall…
Magnetoelectric Response of Antiferromagnetic Van der Waals Bilayers
Chao Lei, Bheema Lingam Chittari, Kentaro Nomura +3
We predict that antiferromagnetic bilayers formed from van der Waals (vdW) materials, like bilayer CrI, have a strong magnetoelectric response that can be detected by measuring…
Signatures of Gate-Tunable Superconductivity in Trilayer Graphene/Boron Nitride Moiré Superlattice
Guorui Chen, Aaron L. Sharpe, Patrick Gallagher +12
Understanding the mechanism of high temperature (high Tc) superconductivity is a central problem in condensed matter physics. It is often speculated that high Tc superconductivity…
